This articles deals with the question why Dutch upper-middle-class parents resort to fee-paying private education, a tiny, recently developed sector of the Dutch educational system. The research is based on interviews with 37 parents and 20 students attending private schools, and on a survey among 376 parents involved in private schooling. From the data is concluded that 'lack of discipline' is the main reason for parents and students alike to choose a private school. Failing to succeed in secondary school lessens the chances of reproduction of parental class position. Analysis of the interviews shows that the parental style of upbringing, marked by negotiation and mutual consent, can make it difficult to acquire the discipline that is needed to follow a successful educational career. Moreover, parents criticize the regular schools for their lack of discipline on the one hand, attention to individual needs on the other. The private schools, characterized by strict rules, permanent supervision, and intense engagement with students, take over the discipline neither parents nor regular schools can provide. In that way, students are able to qualify for tertiary education, needed to ward off future downward mobility.
